摘要： A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.

摘要： A robotic cleaner includes a housing, a suction conduit with an opening, and a leading roller mounted in front of a brush roll. An inter-roller air passageway may be defined between the leading roller and the brush roll wherein the lower portion of the leading roller is exposed to a flow path to the suction conduit and an upper portion of the leading roller is outside of the flow path. Optionally, a combing unit includes a plurality of combing protrusions extending into the leading roller and having leading edges not aligned with a center of the leading roller. Optionally, a sealing strip is located along a rear side of the opening and along a portion of left and right sides of the opening. The underside may define side edge vacuum passageways extending from the sides of the housing partially between the leading roller and the sealing strip towards the opening.

摘要： A surface cleaning head with a leading roller may be used to facilitate capturing of debris in the air flow into a suction conduit on the underside of the surface cleaning head. The leading roller is generally positioned adjacent to and in advance of the opening of the suction conduit. The surface cleaning head may have dual agitators—a leading roller and a rotating brush roll—with the leading roller being located in front of the brush roll. The leading roller may have a smaller diameter than the brush roll and may provide a softer cleaning element. The leading roller may also have a bottom portion exposed to the flow path to the suction conduit and at least a top half that is not exposed to that flow path. The leading roller may also float relative to the surface cleaning head and/or may be adjustable relative to the brush roll.

摘要： A docking station for a robotic vacuum cleaner may include a suction motor, a collection bin, and a filter system fluidly coupled to the suction motor. The suction motor may be configured to suction debris from a dust cup of the robotic vacuum cleaner. The filter system may include a filter medium to collect debris suctioned from the dust cup, a compactor configured to urge a first portion of the filter medium towards a second portion of the filter medium such that a closed bag can be formed, and a conveyor configured to urge the closed bag into the collection bin.

摘要： A surface cleaning apparatus provides a lower profile surface cleaning head by moving at least the suction motor out of the surface cleaning head. The suction motor may be located in an upper portion (e.g., in a wand) pivotably coupled to the surface cleaning head and fluidly connected to a cyclone assembly located in the surface cleaning head. The cyclone assembly may include first and second opposing cyclones with smaller diameters (e.g., as compared to a single cyclone used in existing “all in the head” vacuums) to provide a lower profile with substantially the same or better performance

摘要： An example of a system, consistent with the present disclosure, may include a motor-battery assembly. The motor-battery assembly may include a housing defining one or more cavities, a suction motor configured to be fluidly coupled to a debris compartment of a vacuum cleaner for generating air flow through the vacuum cleaner for entraining debris, one or more batteries at least partially disposed within at least one of the one or more cavities, and a motor/battery controller at least partially disposed within at least one of the one or more cavities, the motor/battery controller configured to control power provided to the suction motor and to regulate charging and/or discharging of the one or more batteries.

摘要： In general, the present disclosure is directed to a hand-held surface cleaning device that includes circuitry to communicate with a robotic surface cleaning device to cause the same to target an area/region of interest for cleaning. Thus, a user may utilize the hand-held surface cleaning device to perform targeted cleaning and conveniently direct a robotic surface cleaning device to focus on a region of interest. Moreover, the hand-held surface cleaning device may include sensory such as a camera device for extracting three-dimensional information from a field of view. This information may be utilized to map locations of walls, stairs, obstacles, changes in surface types, and other features in a given location. Thus, a robotic surface cleaning device may utilize the mapping information from the hand-held surface cleaning device as an input in a real-time control loop, e.g., as an input to a Simultaneous Localization and Mapping (SLAM) routine.

摘要： In general, the present disclosure is directed to a force-sensing arrangement for use in surface cleaning devices, such as a vacuum device, that allows a user-supplied force to be translated into a command signal to cause the surface cleaning device to accelerate forward, reverse or to veer/turn in a desired direction. In an embodiment, the surface cleaning device includes a nozzle, wheels, motor(s) to drive the wheels, and an upright handle portion. The surface cleaning device includes a force-sensing arrangement with load cells coupled at a position where user force is transferred from the upright portion to the nozzle. The force-sensing arrangement detects the user supplying a relatively small amount of force and translates the same into measurement signals. A controller coupled to the load cells utilizes the measurement signals to determine or “infer” a desired direction of travel.

摘要： An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.
